标题: iOS 8 : Get title of song being played by the system music player

我正在尝试获取默认音乐应用当前正在播放的歌曲的标题。方法如下:

- (NSString*)getSongTitle {
  MPMediaItem *currentSong = [[MPMusicPlayerController systemMusicPlayer] nowPlayingItem];
  _title = [currentSong valueForProperty"MPMediaGroupingTitle"];
  NSLog(_title);
  return _title;
}

我在网上阅读的所有内容都表明这应该是正确的，但是 _title 每次都被分配 nil 。有什么想法吗？

顺便说一句，我有@imported MediaPlayer。

Best Answer-推荐答案

我认为您只是使用了错误的 key 。试试 MPMediaItemPropertyTitle。它应该看起来像这样:

- (NSString*)getSongTitle {
  MPMediaItem *currentSong = [[MPMusicPlayerController systemMusicPlayer] nowPlayingItem];
  _title = [currentSong valueForProperty:MPMediaItemPropertyTitle];
  NSLog(_title);
  return _title;
}
